PRI 108: Combined registration of the Adobe-Japan1
collection and of sequences in that collection

A submission for the "Combined registration of the Adobe-Japan1
collection and of sequences in that collection" has been received by
the IVD registrar. This submission is currently under review according
to the procedures of UTS#37, Ideographic
Variation Database, with an expected close date of
2007-11-25. This submission is a revision of
PRI 98.

At the end of the review period, the submission has been incorporated into the 2007-12-14 version of the IVD, with minor adjustments, as 14,647 registered IVSes.

The Adobe-Japan1 Character Collection is widely used as the basis
for the glyph complement of fonts for the Japanese market. Successive
versions of the collection are identified by appending a
supplement number, e.g. Adobe-Japan1-6 (the most current
supplement).

Note that all Adobe-Japan1-6 kanji, except those twenty seven pointed out
above, are given IVS assignments, including those that have only one
form assigned. This is to ensure that each Adobe-Japan1-6 kanji can be
uniquely and explicitly identified without referencing their default
(IVS-less) encoding, and because kanji may be added in future
Adobe-Japan1 Supplements that may be variants of such kanji. As an
example, observe the single line for the kanji assigned to U+3405 in
the collections file: 3405 E0100; Adobe-Japan1; CID+15387

Also note that the highest IVS that is used in U+E010E. It is used
with U+9089, meaning that fifteen kanji are assigned to it, and are to
be distinguished through the use of IVSes. Below are all fifteen lines
for U+9089:

Representative glyphs for the submitted sequences are available in
PDF format, in two sets of charts. Both sets show the sequences
indexed by their base character, in code point order. The complete charts (4.4MB) show all the
submitted sequences. The partial
charts (776KB) show only the characters for which multiple
sequences are submitted.
